"It's great to have Brian back," Patriots offensive coordinator Josh McDaniels said, according to the Kansas City Star. "He's a very good football coach, very knowledgeable and can help us in a lot of different ways. Certainly having another set of eyes with experience and has a lot of understanding of our system and how we go about doing things, I think, is only a positive for us and can help our football team going forward. I look forward to doing that with Brian."
McDaniels himself served a similiar role with the Patriots in last season's playoffs, with the agreement that he would become offensive coordinator when Bill O'Brien took the Penn State head-coaching job.
